Step 1 — Base 10 to decimal

Each digit is multiplied by base 10 raised to its position, then the products are summed.

2 (=2)2 × 10² = 200

5 (=5)5 × 10¹ = 50

5 (=5)5 × 10⁰ = 5

Decimal total = 255

Step 2 — Decimal to base 16

Repeatedly divide 255 by 16; the remainders, read from bottom to top, form the result.

Division	Quotient	Remainder
255 ÷ 16	15	15 → F
15 ÷ 16	0	15 → F

Reading the remainder digits from the last row up to the first gives the converted value.
